Robot Cleans Hospital Rooms With UV Light

A robot that uses ultraviolet light can kill up to 70 percent of bacteria in hospital rooms in just 12 minutes. The device—which bears a striking resemblance to the fictional robot in Star Wars known as R2-D2—has a large saucer-shaped head on top of a column that rises up to reveal a bulb filled with xenon gas. …. The new study, published in the American Journal of Infection Control, looked at the effectiveness of UV light disinfection by itself and found that in just 12 minutes the Xenon UV light system cut the amount bacteria in the room by about 70 percent—roughly the same level of effectiveness as manual disinfection. Hospitals shouldn’t use the UV light system by itself, Jinadatha says, but it has value as a “safety net” to kill bacteria that traditional cleaning may miss. Currently, the system is being used in 40 Veterans Affairs hospitals across the country and about 200 private hospitals…. Of particular note was the fact that manual disinfection plus UV light killed 99 percent of the bacteria that cause MRSA….
